a kuadrat = 4,5 × (8+4,5)

b kuadrat = 8 x (8+4,5)

c kuadrat = 8 x 4,5

a kuadrat = 4,5 x 12,5 = 56,25

b kuadrat = 8 x 12,5 = 100

c kuadrat = 8 x 4,5 = 36

a = 7,5

b = 10

c = 6

a+b+c = 7,5+10+6 = 23,5

Jawabannya

${b}^{2} = 8 \times (8 + 4.5) \\ {b}^{2} = 8 \times 12.5 \\ {b}^{2} = 100 \\ b = \sqrt{100} \\ b = 10$

${a}^{2} = 4.5 \times (4.5 + 8) \\ {a}^{2} = 4.5 \times 12.5 \\ {a}^{2} = 56.25 \\ a = \sqrt{56.25} \\ a = 7.5$

${c}^{2} = 4.5 \times 8 \\ {c}^{2} = 36 \\ c = \sqrt{36} \\ c = 6$

a + b + c

= 7,5 + 10 + 6

= 23,5 cm

Jadi, jawabannya 23,5 cm
